An old enemy of Marshal Micah Torrance arrives in town, bent on revenge. Knowing that Micah's crippled arm makes it difficult for him to use a six-shooter, the enemy assumes he can best Micah in a gunfight; however, he soon learns that Micah has developed the habit of carrying a shotgun wherever he goes. The enemy decides to wait out Micah, knowing that sooner or later he will put down the shotgun. Lucas is wounded when he tries to interfere and help the Marshal, but he and Micah concoct a trick that they hope will improve Micah's chances in a gunfight.
